Custom glass wind guards are cut to order and almost never returnable, so one sloppy measurement turns a $100-plus accessory into scrap. Measuring right takes five minutes: identify the shape, measure the opening (diameter for round, length and width for rectangular), capture the depth and height, and add the 2.5-inch margin guards need to clear the burner. Here is exactly what to record before you order.
TL;DR: To size a fire pit wind guard, measure the burner opening (diameter for round pits, length by width for rectangular), the depth from outer to inner edge, and the height from the ground to the opening. Order a guard at least 2.5 inches larger than the opening; standard heights run 6 to 18 inches.
Work through five measurements in order, and write each one down as you go. A wind guard surrounds the burner pan and blocks the breeze that would otherwise blow your flame off-center or out, so precision here is what makes the difference between a guard that fits flush and one that leaves gaps.
The shape decides how many numbers you record. Round pits, the most common style, need only the diameter, measured across the center. Rectangular pits and fire tables need both length and width to size the panels correctly.
Watch for a raised edge or lip around the inner burner pan, common on gas pits and fire tables. If one is present, measure from the outer raised lip rather than the burner pan, so the glass clears the edge and sits flush with the top opening. Using a round guard on a rectangular pit, or the reverse, leaves gaps that fail to block wind and create a safety hazard, so always match the guard to your pit’s shape.
Order a wind guard at least 2.5 inches larger than the fire pit opening, and expect standard heights to fall between 6 and 18 inches. That margin gives the flame room to breathe while still blocking the wind, and the height range covers most residential pits and tables.
When you place a custom order, hand the fabricator the full set: shape, diameter or length by width, depth, height, and your photos. Tempered glass is the standard material because it resists heat and stays clear, but it can only be cut accurately from exact dimensions. Double-check, even triple-check, every number before you commit, because there are no do-overs on a custom cut. If you are still choosing a pit or a table to pair a guard with, our fire pit buyer’s guide covers the shapes and burner styles that wind guards fit best.
A wind guard surrounds the burner and blocks breezes that blow the flame off-center or snuff it out, keeping the fire stable and even. It also helps keep the flame away from people and objects, and the tempered glass adds a clear, finished look to a gas pit or fire table.
Yes. Many makers cut custom glass guards for round, rectangular, square, or irregular pits. Provide exact measurements and photos, and a fabricator can build a guard to fit dimensions that no off-the-shelf size matches.
Most are. Tempered glass is durable and heat-resistant, and it stays clear so you can still see the flame. The panels typically attach with a simple bracket system that secures the glass around the burner.
No. A round guard on a rectangular pit (or the reverse) leaves gaps that let wind through and can create a safety hazard. Always order a guard cut to the specific shape of your fire pit.
Standard wind guards run 6 to 18 inches tall. The right height depends on your pit’s depth and how exposed your space is, so a shallow pit on a breezy patio benefits from a taller guard, while a deep pit needs less.
